`IMPRcvE|v`|ENT IN GRAlN-,Bmoeus Specification formirg partof Letters Patent No. 102,815, dated May 10,1870. y

To all whom it may concern:

Beit known that we, W. D.BARRAH, lIRA MtGIEFORD, and EDWARD T. JOHNSTON, alll of Davenport, Scott county, inthe State of Iowa, have invented a new and useful 1msame, the seat being removed. f

Our invention has-for its object to furnish an improved machine for forming. grain into bundles andibinding it as it passes from the reaper, which shall be simple in construction, effective v1n operation, and convenient in use and 1t consists in the construction and combination of the various parts of the machine,-

as hereinaftermore fully described.

A is the frameof the binder, the forward4 end of whichis attached to the rear part of the frame of the reaper in such alpositi'on as' to receive the grain as itis raked from the platform of the said reaper. Thev frame A is supported upon the axle B, which revolves in bearings attached to the said frame A, and to yhe ends of which the wheels C are securely rttached, so as to carry the' said axle with .hem in their revolution. To one of the wheels ll or to the axle B is attached a pulley, D, round which passes the band E. The band also@ passes around the pulley F, attached to. the projecting end of the'jonrnal of the roller G, which revolves in bearings in the rear .u't of the platform, formed iu the forward` Virt of the frame A. H is an endless apron, nich passes around the roller Grv and around roller, I, the journalsof which revolve in carings attached to the forward part of the ame A. The endless apron H may have 'goss-bars h attached to it to assist in carrytug back thegrain as it is received from the yrea-per. The forward part of the frame A is covered with a tapering hood or bonnet, J, which draws the grain together as it is being carried hack, tops foremost, by the endlessapron H.l

K is a set of four concave rollers, :having bevelgear -wheels formed upon their'ends, the teeth of which mesh into each other,so thatthey may allrevolve together and in the same direction.. The journals of the rollers K yrevolve in bearings in theverticalframe L, securely attached to theframe Ain such a position that the rollers K may receive the grain from the tapering lhood or bonnet J, and-draw it lfarther back, and, at the saune time, press it more closely together so that it may euteirthe next set of rollers. --To theprojecting end of the journal of the .lower roller Kjis attached agear-'wheel,.-M, the teethof' which meshv into the teeth of the .gear-Wheel vN attached to the drive-wheel C er axle B, sothatthe rollers K may be revolvedby the advance of the machine.v

0 is another set ot' concave rollers, simi'- lar to the rollers K, but smaller, connected lo each other, and made/to revolve togetherby bevel-gear wheels formed upon their. ends, 'andthe teeth of which.l mesh into each other. The journal-s of the rollers O revolve in bearings in the` vertical frame P, attached to the frame A at such a 'position in' the rear ofthe frame L that the rollers'O may receive the vgevel from` the rollers K, farther compress it, and carry it back to andv force it through the short tube Or thimble. 'To the projecting end vof one of the journals of the lower roller 0 is attached a, gear-wheel, Q, the teeth ot'whieh mesh into the teeth of the gear-wheel Nattached to thedrive-wheel C or axle B, as hereinbefore described, so that the second set of rollers may also be"revolved by the advance of the machine. l

The rollers K and 0 may be concave `or cylindrical, and corrugated, iiuted, orplain, as maybe desired; but we prefer to make them concave and iiuted, as working more satisfacf torily.

R is the sheaf-tube or thimble, that receives the gavel from the rear set of rollers O, and which is.l supported from the-frame P by the arms or brackets S, as shown in Figs. 1 and 2. The tube R is made ot such a length as to allow a dozen, more or less, of the bands T to.

be placed uponl it, one of which bands T as each gavel passes ont of the tu be R, is slipped from the tube R upon the said gavel, which band will be tightened by the expansion of the gav'el, as it escapes from the tube R, so that .the bundle will drop tothe ground beneath the operator-s seat U, thoroughly bound. The operators seat U is attached to' the rear i end ofthe frame A in such a position that he t-ached tubes V may be slipped upon it, and

the bands slipped from the tube V upon the gavel in the same manner as they were slipped :from the said tube R.' The tubes V when not in use may rest upon the stands W, attached to the frame P Vin such positions that the op- `erator may convenientlyreach them to. place bands'npon them as he has time, so that one or both'ot' them maybe kept filled withbands v ready' for use.

Xare stands attached` to the rear parts of 'the side bars of the frame A in such positions as to be conveniently reached by the operator to remove the'bands frolnthem to placethem upon the tubes R and V, as required. The stands X should be capable of carrying several hundreds of the bands.

The bands T are all preparedor tied previcusly, and are taken to the eld ready for use.

As it is immaterial how many knots there may be in the bands, old bands'when cut from the bundles may be retied and used again.

It" sometimes happens that a bundle of grain may pass from the machine smaller than the bands T will bind closely. On this account we prefer to use the looped or slip bands` T. The bands T are so formed, as shown in Fig'. 2, that when a small bundle passes from `the machine the attendant, by drawing upon the loose or projecting` end of said band, may draw it closely around the bundle.

The end of the band T' has a knot formed upon it, as shown in Fig. 2,- in such a position that.4 when the other end is slipped out to said machine, so'that itsweight will rest almost entirely upon the axle and wheels B C.

Having thus described our invention, we claiin as new and desire to secure by Letters Patentl 1. The tapering bonnet or hood J, endless apron H, and two or more sets ofrollers, K O, in combination with each other and with the frame A, axle B,'and wheels C, substantially as herein shown and described, and for the purpose set forth.

2. The apron H, rollers K O, combined and arranged with relation to each other, andthe axle C B, so as to operate in the .manner described, for the purpose specified.

3. The band'tube R, arranged with relation to the rolls K 0, bonnet or hood J, and endless apron H, all as shown and described.

4. The detached thimbles or band-tubes V adapted to receive the endless bands T and to be placed upon the stationary band-tube R,

substantiallyas herein shown and described, and for the purpose set forth.

5. The stands W, adapted to receive and hold the thimbles or detached band-tubes V,

` substantially as herein shown and described,

and for the purpose set forth.
